LiquidSpace, the two-pronged workspace solutions platform, announced today that it has raised $1.3 million in follow-on investment to the $6 million raised in the company’s second round of funding that closed earlier this year.

Founded in 2010, the San Francisco-based company serves two sets of customers: modern professionals who use the platform to book office or meeting spaces instantly, and companies who employ LiquidSpace to manage their workforce’s workspace needs. It boasts over 2,000 workspaces and meeting rooms in over 250 U.S. cities. It has facilitated over 200,000 reservations thus far.

The follow-on investment comes from two strategic partners: Steelcase and CBRE Group. Both have global experience in workplace strategy and commercial real estate.

“We are thrilled to have the support of Steelcase, the global leader in the office furniture industry and CBRE, the world’s largest commercial real estate services and investment firm [in terms of 2012 revenue], as we work with Fortune 500 companies to provide a clean, simple solution for evolving their real estate portfolio and workplace strategy,” said Mark Gilbreath, the founder and chief executive of LiquidSpace. “We look forward to leveraging their insights and experience to advance a demand-driven model that reduces costs for companies and provides employees with more choices and reliable workspace options.”

For the modern professionals, the company provides a web portal and mobile applications through which they can access LiquidSpace’s services. It not only provide workspaces but also collects data and helps customers make smarter workplace decisions based on actual utilization information.

In January, LiquidSpace raised $6 million in second round funding led by GPT Group, with participation from previous investors Shasta Ventures, Floodgate Fund, and Greylock Capital. The total funding to date is $12.385 million.
